- You had a bad thing that day.
- You were having a bad thing that day.
Could you tell me the difference in meaning between sentence 1 and sentence 2? I feel there must be a difference in meaning.
The implied meaning is:
You had a bad thing happen that day.
The verb should be had happen. happen could be omitted in informal speech.
With only had as the verb (as in your example), it would mean you possessed a "bad thing". Unlikely, but we would need to know what the "bad thing" was, in context.
